There’s a party at Google’s headquarters right now, as the company’s developers have finally managed to push out the stable version of the AngularJS 2.0 JavaScript framework.
Work on Angular 2 began in the autumn of 2014, and it was initially planned for a public release in the autumn of 2015. As with any project of this size, development dragged on, and the final version was postponed from quarter to quarter.
The framework that revolutionized web development after it came out in October 2010 has been rewritten from scratch using Microsoft’s TypeScript language and features enhanced performance and a smaller footprint.
The cost for all improvements is a lot of broken code. Angular 2.x is not backward compatible with Angular 1.x applications, and even if Google has tried to make the migration process less painful, developers are expected to rewrite a large chunk of their JavaScript code when upgrading to the new version.
Among the new features added to Angular 2, we mention ahead-of-time compilation, built-in lazy loading, the new Angular CLI, and an Angular styleguide. Angular 2 also features ES5 and ES6 support, React Native and NativeScript integration.
